+ * Parse a .fun source file and compile it into entry bytecode.
+ * Minimal support:
+ *  - Optional shebang on the first line.
+ *  - Optional single function wrapper: fun <ident>() { ... }
+ *  - print("...") statements inside function or at top-level.
+ * Produces bytecode that executes all discovered print statements and halts.
+ *
+ * Returns: newly allocated Bytecode*, or NULL on error.
